December 2003: CIA Reduces Time Limit on Standard Technique of Sleep Deprivation
The CIA reduces the period for which detainees can be deprived of sleep during the application of one of its standard techniques. Previously, if detainees were subjected to sleep deprivation as a part of a standard interrogation technique, the application could go on for 72 hours (see November 2002). However, the maximum is now reduced to 48 hours. Detainees are also subjected to sleep deprivation as a part of enhanced techniques, in which case the maximum is 11 days.
